Description

dbx_connect() returns an object on success, FALSE on
error. If a connection has been made but the database could not be
selected, the connection is closed and FALSE is returned.
The persistent parameter can be set to
DBX_PERSISTENT, if so, a persistent connection will be
created.

The module parameter can be either a string or a
constant, though the latter form is preferred. The possible values are
given below, but keep in mind that they only work if the module is
actually loaded.

DBX_MYSQL or "mysql"

DBX_ODBC or "odbc"

DBX_PGSQL or "pgsql"

DBX_MSSQL or "mssql"

DBX_FBSQL or "fbsql" (available from PHP 4.1.0)

DBX_SYBASECT or "sybase_ct" (available from PHP
4.2.0)

DBX_OCI8 or "oci8" (available from PHP 4.3.0)

DBX_SQLITE or "sqlite" (PHP 5)

The host, database,
username and password
parameters are expected, but not always used depending on the connect
functions for the abstracted module.

The returned object has three properties:

database

It is the name of the currently selected database.

handle

It is a valid handle for the connected database, and as such it can be
used in module-specific functions (if required).
